I am an Assistant Professor in Math Education in the School of Education at Boston University. My research focus in on the quality and structure of mathematics curriculum as found in textbooks, lesson plans, and enacted in classrooms.
I received my PhD from Michigan State University and my dissertation is titled "The Mathematics Textbook as a Story: A Novel Approach to the Interrogation of Mathematics Curriculum." Directed by Dr. Glenda Lappan and Dr. Nathalie Sinclair, it introduces and analyzes a theoretical framework of mathematics curriculum as a story with mathematical characters (objects), action (procedures), setting (representation), moral (resulting message to the reader), and plot (the effect of the revealing and restriction of information throughout the text on the reader).
In addition to my research, I teach prospective teachers how to teach mathematics (commonly referred to as "methods") and pedagogical content courses, such as Geometry for Teachers. I draw from my experience as a high school teacher at Phillip and Sala Burton Academic High School in San Francisco, where I taught math for 17-years.
I also am the lead author of several math textbooks from grades 6 - 12 that focus on metacognitive development, conceptual development, and problem solving. These textbooks, such as Algebra Connections, are published by a non-profit called CPM Educational Program. I also serve as CPM's Director of Curriculum and on its Board of Directors.
